発明が解決しようとする課題Problems to be solved by the invention

従来の自転車用チャイルドシートは自転車本体に強固にねじ止めされて車体と一体化しているか、取外しができても、かなりの重量と大きさがあるので自転車を折り畳んで携行する場合チャイルドシートの携帯及び取付けは困難であるという問題があった。  Even if a conventional bicycle child seat is firmly screwed to the bicycle body and integrated with the car body or can be removed, it has a considerable weight and size, so if you fold and carry the bicycle, carrying and attaching the child seat is There was a problem that it was difficult.

さらに従来の自転車用チャイルドシートは重いため自転車総重量を増加させ自転車の加速性能を悪化したり、横幅が大きいため駐輪場で場所を取ってしまうという問題点があった。  Furthermore, conventional bicycle child seats are heavy, so that the total weight of the bicycle is increased to deteriorate the acceleration performance of the bicycle, and the lateral width is large, so that there is a problem that it takes up space in a bicycle parking lot.

本発明は、上記問題点を解決することを課題とする。具体的には足乗せ部とハンドルバーが容易に着脱ができ携帯可能な軽量のチャイルドシートを提供することを課題とする。更に、本発明は足乗せ部とハンドルバーが容易に着脱ができ携帯可能かつ足乗せ部が2つに折り畳めるので駐輪時に幅を取らない軽量のチャイルドシートを提供することを課題とする。  An object of the present invention is to solve the above problems. Specifically, it is an object of the present invention to provide a lightweight child seat in which a footrest portion and a handle bar can be easily attached and detached and portable. Another object of the present invention is to provide a lightweight child seat that can be easily attached and detached from the footrest and the handlebar and that is portable and that does not take up a width when parked because the footrest can be folded in two.

課題を解決するための手段Means for solving the problem

上記の問題点を解決するために、本発明は着脱携帯可能な足乗せ部とハンドルバーを設けることとしている。  In order to solve the above problems, the present invention is provided with a detachable and portable footrest and a handle bar.

足乗せ部は自転車フレームのトップチュープに噛んで挟む状態で取付けられ、合成ゴムのバンドあるいは簡単なネジによって車体にしっかりと締結される。さらに車体に装着する部分は合成ゴムあるいはウレタンシートを介することにより車体が傷つくのを防ぐと共に、滑って取付け位置がずれることを予防する。また、足乗せ部は蝶番構造を有し、2つに折り畳むことによって自転車駐輪時に横幅を取ってじゃまになってしまうことを防ぎ、取外した時もバッグなどに収納して持ち運びし易くなる。さらに足乗せ部は2ヶ所のネジを調節することによって高さと角度が変えられるため、個々の子供に対し、あるいは個々の自転車に対して足乗せ部の適正位置の設定が可能である。  The footrest is attached to the top of the bicycle frame so as to be pinched and fastened to the vehicle body with a synthetic rubber band or a simple screw. Furthermore, the part to be mounted on the vehicle body prevents the vehicle body from being damaged by using a synthetic rubber or urethane sheet, and prevents the mounting position from slipping. The footrest has a hinge structure and is folded in two to prevent it from getting in the way when parked on a bicycle, and when it is removed, it can be stored in a bag and carried easily. Furthermore, since the height and angle of the footrest can be changed by adjusting two screws, it is possible to set the appropriate position of the footrest for each child or each bicycle.

ハンドルバーは同乗する子供が把持するためのもので自転車本体のハンドル部に噛んで挟み簡単なネジによって固定される。ネジを緩めることによって着脱可能で取外して持ち運ぶこともできる。The handlebar is intended to be gripped by a child who rides it, and is bitten by the handle portion of the bicycle body and fixed with a simple screw. It can be removed and carried by loosening the screw.

チャイルドシート専用サドルは瓢箪形で縦長な独特の形態を有し、これは前方に子供が、後方に大人が着座するようになっている。また、子供が着座する部分には子供の下腹部を横方向に締めるバンド方式の安全ベルトが取付けられている。このチャイルドシートは大人用のサドルと一体化することによって軽量かつ簡便化が実現されている。  The child seat saddle has a unique shape that is saddle-shaped and vertically long, and is designed to seat a child in the front and an adult in the rear. A band-type safety belt for fastening the child's lower abdomen laterally is attached to the portion where the child is seated. This child seat is lightweight and simplified by being integrated with an adult saddle.

発明の実施と形態Embodiments and embodiments of the invention

以下、本発明の実施の形態について説明する。  Embodiments of the present invention will be described below.

図1は、本発明の自転車用チャイルドシートを取付けた自転車を示す斜視図である。図1に示されるように、本発明の自転車用チャイルドシートは、足乗せ部(1)、ハンドルバー(2)、及び専用サドル(3)から構成される。  FIG. 1 is a perspective view showing a bicycle to which a bicycle child seat according to the present invention is attached. As shown in FIG. 1, the bicycle child seat according to the present invention includes a footrest (1), a handlebar (2), and a dedicated saddle (3).

足乗せ部(1)は、自転車のフレームのトップチューブに噛んで挟む状態で足乗せ部固定用の合成ゴムのバンド(4)によって取付けられる。これにより足乗せ部は自転車本体に簡単に着脱可能となる。  The footrest portion (1) is attached by a synthetic rubber band (4) for fixing the footrest portion in a state where the footrest portion (1) is nipped and pinched by the top tube of the bicycle frame. As a result, the footrest part can be easily attached to and detached from the bicycle body.

ハンドルバー(2)は大人といっしょに同乗する子供が使用するもので、自転車本体のハンドル部に噛ませて挟み簡単なハンドルバー固定用のネジ(5)によって装着される。このハンドルバーも足乗せ部同様、ネジ(5)を緩めることで簡単に着脱可能になり取外して持ち運ぶことができる。  The handlebar (2) is used by a child who rides with an adult. The handlebar (2) is attached by a handlebar fixing screw (5) that is easily held between the handlebars of the bicycle body. As with the footrest, this handlebar can be easily detached by removing the screw (5) and can be removed and carried.

専用サドル(3)は前方に子供が、後方に大人が着座するため瓢箪形で縦長な独特の形態を有している。子供が着座するシートの部分には子供の下腹部を横方向に締めるバンド方式の安全ベルト(6)が装備されている。  The dedicated saddle (3) has a unique shape that is saddle-shaped and vertically long because a child sits on the front and an adult sits on the rear. A band-type safety belt (6) for fastening the child's lower abdomen laterally is mounted on the seat on which the child is seated.

図2は、本発明の自転車用チャイルドシートの足乗せ部の前方面観の断面図である。足乗せ部は大きく2つの部品からなる。1つは足を乗せるステップ部で、もう1つは自転車に取付ける本体部である。  FIG. 2 is a cross-sectional view of the front view of the footrest portion of the bicycle child seat according to the present invention. The footrest part is mainly composed of two parts. One is a step part to put a foot on, and the other is a main body part attached to a bicycle.

ステップ部は蝶番構造で蝶番軸(7)を有し、2つに折り畳むことができる。この機能により、自転車駐輪時に横幅を取ってしまって止めづらくなることが無くなり、取外した場合もバッグなどに収納して持ち運びし易くなる。またステップ部の縦軸板を本体部に挟み込み、足乗せ部のステップ部と本体部を連結固定するネジ(8)により足乗せ部は一体化される。  The step portion has a hinge structure and has a hinge shaft (7) and can be folded in two. With this function, it is no longer difficult to stop the bicycle when parked and difficult to stop, and even when removed, it is easy to carry in a bag or the like. Moreover, the footrest part is integrated by a screw (8) that sandwiches and fixes the step part of the footrest part and the main body part by sandwiching the vertical plate of the step part between the body part.

本体部は自転車フレームのトップチューブに噛んで挟む状態で取付けられ、合成ゴムのバンド(4)を自転車フレームのトップチューブに巻き付けることで固定される。足乗せ部本体の左右には合成ゴムのバンド(4)を引っ掛け、固定するための止具(9)が装備されている。また、足乗せ部の本体部が自転車フレームに密着する部分にはウレタンシート(10)が介在する。このことにより、自転車フレームが傷付くことなく、足乗せ部がずれることなく固定される。  The main body is attached in a state of being bitten and sandwiched by the top tube of the bicycle frame, and is fixed by winding a synthetic rubber band (4) around the top tube of the bicycle frame. Stoppers (9) for hooking and fixing a synthetic rubber band (4) are provided on the left and right of the footrest body. Further, a urethane sheet (10) is interposed at a portion where the main body portion of the footrest portion is in close contact with the bicycle frame. As a result, the bicycle frame is not damaged and the footrest is fixed without shifting.

図3は、本発明の自転車用チャイルドシートの足乗せ部の側方面観の透視図である。足乗せ部のステップ部は足乗せ部の本体部と前後2つのネジ(8)によって連結固定される。また、ステップ部の位置を決める高さと角度は、これらのネジ(8)によって任意に調節が可能である。本体部は合成ゴムのバンド(4)を自転車フレームのトップチューブに巻き付け、止具(9)に引っ掛けて固定する。止具(9)はネジの場合もあり得るが、簡単に合成ゴムのバンド(4)を取外し出来るものではなくてはならない。  FIG. 3 is a perspective view of a side view of a footrest portion of a bicycle child seat according to the present invention. The step portion of the footrest portion is connected and fixed to the main body portion of the footrest portion and the two front and rear screws (8). Further, the height and angle for determining the position of the step portion can be arbitrarily adjusted by these screws (8). The main body is fixed by hooking a synthetic rubber band (4) around the top tube of the bicycle frame and hooking it on the fastener (9). The fastener (9) can be a screw, but it must be able to easily remove the synthetic rubber band (4).

図4は、本発明の自転車用チャイルドシートを取付けた自転車の側方面観図である。同乗する子供の体位を点線で示している。この発明のチャイルドシートの使用は、自分で補助輪なしで自転車に乗れると思われる年齢である5歳ぐらいから9歳ぐらいまでの子供を対象と考えている。  FIG. 4 is a side view of the bicycle to which the bicycle child seat of the present invention is attached. The position of a child traveling with him is indicated by a dotted line.
